Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that, in order to just
Part related to the present invention rather than entire infrastructure are illustrate only in description, accompanying drawing.
Embodiment one
Fig. 1 is a kind of flow chart for Application on Voiceprint Recognition performance improvement method that the embodiment of the present invention one is provided, and the present embodiment can
Situation suitable for controlling smart machine by phonetic order, this method can be performed by Application on Voiceprint Recognition performance boost device,
The Application on Voiceprint Recognition performance boost device can be realized by the way of software and/or hardware.With reference to Fig. 1, this method specifically can be with
Including as follows：
S110, the voice open command for obtaining user's input.
Intelligent terminal can be detected that intelligent terminal in a dormant state detects residing ring in real time to surrounding environment
When there is phonetic order in border, the voice open command of user's input is obtained.Intelligent terminal is support interactive voice with multimedia
The smart machine of function, such as has the function of supporting in terms of audio, video, data, can be intelligent robot, intelligent sound box
Deng.
S120, determine voice open command with it is default guiding text whether match；If matching, continues executing with S130；
Otherwise, execution S160 is redirected.
Wherein, guiding text refers to that the voice that validated user is pre-set wakes up the corresponding text of instruction, and voice, which wakes up, to be referred to
Make for controlling intelligent terminal to be in a dormant state switched to running status.For example, using intelligent terminal in validated user
During such as intelligent terminal first by use, the personalized voice of prompting user's input wakes up and instructed, voice is waken up and referred to
Order carries out the guiding text that semantic analysis obtains personalization.
If specifically, voice open command and guiding text matches success, active user is probably the conjunction of intelligent terminal
Method user, continues executing with subsequent operation；If voice open command and guiding text matches failure, active user will not be legal
User, can directly shield the voice open command.
S130, the corresponding vocal print feature of extraction voice open command.
S140, the vocal print feature of extraction matched with predetermined sample vocal print feature, wherein sample vocal print is special
Levy is extracted in advance from the semantic voice messaging for guiding text；If the match is successful, S150 is continued executing with；Otherwise, jump
Turn to perform S160.
Wherein, the determination of the sample vocal print feature can include：During voiceprint registration, provide a user in recording
Pass passage；Show personalized speech input prompting message；The personalized speech content that user inputs is analyzed, obtains described
The sample vocal print feature of user.
It should be noted that during voiceprint registration, the personalized speech content that user inputs is not especially limited,
Guiding content of text is not especially limited, it is allowed to which user uses personalized guiding text.Also, to personalized speech
Quantity and volume are also not construed as limiting, and user carries out repeatedly guiding voice typing with can not limiting number of times using multiple usual volumes.
In the range of certain amount, the personalized speech quantity that user inputs during voiceprint registration is more, and personalized speech is entered
The degree of accuracy for the sample vocal print feature that row analysis is determined is higher.Sample vocal print feature is not limited by speech samples amount in the present embodiment
System, improves fault tolerant mechanism, so as to improve the degree of accuracy of sample vocal print feature.
Operation is opened in S150, execution.
S160, without any operation.
It is further to note that intelligent terminal can have multiple validated users, different validated users are to that should have sample sound
Line feature and guiding text, then the incidence relation being also stored between guiding text and sample vocal print feature in intelligent terminal, or
Person is stored with validated user with guiding the mapping relations between text, and validated user and sample vocal print feature.
By taking the opening process of intelligent sound box as an example, the corresponding guiding texts of user A are " intelligent sound box that please start me ", and
Extract the sample vocal print feature for obtaining user A.Guiding text corresponding to user B is " intelligent sound box quickly starts ", and is extracted
Obtain user B sample vocal print feature.User C does not store any open command, guiding text and sample sound to the intelligent sound box
Line feature.During intelligent sound box use, if it is " intelligent sound box that please start me " that user A, which says content to intelligent sound box,
Voice open command, now voice open command and guiding text matches success, and " intelligent sound box that please start me " is corresponding
The match is successful for current vocal print feature and user A sample vocal print feature, and intelligent sound box starts.
However, when user A says the voice open command that content is " intelligent sound box quickly starts " to intelligent sound box, though
Right voice open command and user B guiding text matches success, but current vocal print feature and user B sample vocal print feature
It fails to match, and intelligent sound box starts failure.
The technical scheme of the present embodiment, by obtaining the personalized guiding voice that user inputs, the personalization according to user
Guiding voice extracts the sample vocal print feature for obtaining user, and according to sample vocal print feature to the corresponding vocal print of voice open command
Feature is matched.Due to guiding the content of text can be by user's sets itself, personalization guiding voice improves fault-tolerant machine
System, improves the degree of accuracy of Application on Voiceprint Recognition, so as to improve the degree of accuracy of sample vocal print feature, correspondingly, improves follow-up sound
The degree of accuracy of line characteristic matching, improves Consumer's Experience.
Embodiment two
There is provided a kind of update method of sample vocal print feature on the basis of above-described embodiment one for the present embodiment.Fig. 2 is
The flow chart for a kind of Application on Voiceprint Recognition performance improvement method that the embodiment of the present invention two is provided, as shown in Fig. 2 this method specifically can be with
Including following：
